Gluu is a San Antonio, TX, USA based startup offering a cloud based Identity Service that aims to make it easier for organizations to securely share identity information and to achieve inter-domain web single sign on. The Gluu services are built on open source software such as Apache, Penrose, MySQL database, OpenSSO and OpenDS.

OpenDS, the LDAPv3 directory service in Java, is used for different services in the Gluu infrastructure. It is used for storing all of the users' identity information as well as groups and access control information, in a highly available manner thanks to several instances of OpenDS replicated in a multi-master topology. Also OpenDS is used as a cache layer for some of the Gluu internal data, for availability and performance. Finally OpenDS is also the configuration store for the OpenSSO services. Gluu offers web services access to the LDAP directory services through the OpenDS DSML Gateway, a web application translating DSML messages to LDAP.

OpenDS was chosen over other directory servers for its inherent multi-platform support, its numerous features and its simplicity.

Ten hospital groups across Germany initiated a project to create a reference implementation for recording users of their Health System - an e-Health initiative for Electronic Case Management. The project aims to enhance the communication of electronic case records by specifying a standard for each hospital to follow and GlassFish is a key part of this project.

The reference implementation heavily relies on Web Services for interoperability between the chosen hospitals. The reason for choosing GlassFish over other open source frameworks (for example JBOSS and AXIS2) was for its WSIT support and its promoted Microsoft Interoperability with Microsoft's .Net version 3 WCF technology. If you would like to know more information about WSIT, see the Project Tango Overview.

To read through all of Fraunhofer Gesellschaft's reasons why they chose GlassFish v2, see their full questionnaire here. Here's how Fraunhofer Gesellschaft summarizes their reasons for using GlassFish; Oliver Boehm writes, "The wide development community and the platform independence are the likable benefits".
